Specification of Letters Patent.

Application filed June 29, 1906. Serial No. 324,032.

have invented certain new and useful Im-' provements in Type-VVritingMachines, of which the folloi'ving is a specification.

My invention relates to typewriting machines and more particularly tomechanism for effecting a feed ofstencil plates, cards or like worksheets.

One object of my invention is to provide ellicient mechanism'for quicklyand accurately feeding stencil plates, cards or the like to operativeposition in the machine.

Another object of my invention is to provide means for regulating'thefeed to suit different characters of work or work sheets employed.

A still further object of my invention is to provide efficient means forautomatically discharging the plates, work sheets or cards from themachine after they have been written or perforated.

To the above and other ends which will hereinafter appear my inventionconsists in the features of construction, arrangements of parts andcombinations of devices to be hereinafter. described and plaime In theaccompanying drawings, wherein like reference characters indicatecorresponding parts in the various views, Figure l is a side elevationwith parts broken away i 5 of. one form of machine embodying my in-'vention..

The machine to which I have shown my invention applied in the presentinstance is a stencil making machine which employs a plurality ofstencil cutting type bars or bars provided with points or needlesarranged on each bar in accordance with the character of perforations tobe formed in the stencil plate by the individual type bar and the feedmechanism is intended to feed the stencil plates successively to theprintin or stencil cutting position, to properly feed the plates fromline to line after they have arrived in such position and to feed eachstencil plate out of the machine after it has been completed. It shouldbe understood, however, that my improved feed mechanism may be employedin. connection with ordinary cards, envelops or the like in variousforms of typewriting machines and for convenience I will refer herein tothe stencil plates as cards or Work sheets, though it should beunderstood that these terms are intended to apply generally to differentcharacters of work sheets, whether they be ordinary cards, envelops,stencil plates. or other forms of work sheets, and whet-her they are tobe printed upon in the usual manner or perforated to make stencil platesas in the present construction.

The machine shownin the drawings has a main frame, key levers, type barsand escapement resembling the corresponding parts of the Remingtontypewriter; indeed, these parts of a typewriting machine may be usedwithout change in carrying out my invention.

The frame of the machine comprises a base 1, corner posts 2 and a topplate 3. Key levers 4, provided with the usual finger keys 5, arefulcrumed on a fulcrum bar'6 secured to the base of;the machine. Eachkey leveris pivotally connected at 7 to a link 8, the upper end of whichis pivoted at 9 to a type ar 10 pivoted at 11 to] type type bar carries1- iora tin' needles'oi mts 13 arranged o tlief'character f: theindividual bar which carriedtliem.

Each key when pressed is operative to swing the associated so-calledtype bar 10 to the printing or perforating position so that the points13 will impact against the stencil plate or work sheet and the platen bywhich it is fed, as will hereinafter more clearly appear. Extendingbeneath the key levers 4 is a uni versal bar 14 connected at its ends toupwardly extending links 15 which in turn are connected to the ends of atransverse bar 16 carried by the forwardly extending arm 17 of a dogrocker pivoted at 18 to a depending bracket 19 which is secured to thetop plate. The upwardly extending arm 20 of the dog rocker carries theusual feed dogs 21 which cal er-ate with a feed rack 22 carried byrearwardly extending arms 23 connected with a carriage 24. Said carriagecomprises a substantially rectangular frame having front, rear and. sidebars, as shown in Fig. 2. A restoring spring 25 is connected at one endto the dog rocker and at its opposite end to the depending bracket 19 torestore the dog rocker and the universal bar to the normal position whenpressure is released on the finger key 5.

A spring drum 26 has one end of a band 27 connected thereto, the otherend of said band. being connected to a bracket arm 28 secured to thecarriage. A supporting and guide rod 29 is mounted in u wardly extendinglugs 30 which project mm the top plate and this rod passes looselythrough ears 29% (Fig. 1) projecting from the carriage. Said earsprevent accidental displacement of the carriage, but the weight of thelatter at the rear is carried by grooved rollers 31 mounted on thecarriage and 00- operating with the guide rod 29. The forward side ofthe carriage has aroller 32 journaled in 1: depending block 33, theroller bearing on a fixed track 34, thus sup orting the forward side ofthe carriage. e forward side of the carriage may be raised to inspectthe work or for any other pur- 1059, the connection with the rod 29servmg as a pivot.

The carriage is adapted to move from side to side of the machine, theextent of such movement depending on the length of the work sheets orstencil plates employed. A depression of a finger key will effect astepby-step letter space feed movement of the carriage in the mannerusual in typewriting machines. A cylindrical, rotary platen 35 ismounted upon a shaft 36 supported in bearing plates 37 and 38 whichproject up-' wardiy from the side bars of the carriage 24 and the outerends of said shaft are provided with finger wheels 39 and 40 by whichthe platen may be turned. A longitudinally extending groove or slot 41is formed within the platen throughout the length thereof. A textilecovering of two or more layers 42, 43 surrounds the platen and the ends44, 45

are adapted to be received within the longitudinal groove or slot 41 inthe platen as shown in Fig, 3. A clamping piece or stri 46 is adapted tobe received between the ad jacent ends 44, 45 of the-textile covering,

as shown in Figs. 3 and to clamp or socure the covering in place on theplaten. Outwardly projecting fingers47 are provided on the locking stripin order to remove it to afford a removal of the textileplaten-covering. The textile coverings of e8 to the platen permit theperforating need pass through the stencil sheet. As will appear moreclearly hereinafter, the art of the laten having the slot 41 therein 15never at the bottom next to the work sheet at the time when theperforating of saidsheet is taking place.

A serrated or toothed feed wheel 48 is formed on the platen head at eachend of the platen in order to engage the stencil plates and feed themforward as the platen rotated, as will hereinafter more clearly ap pear.A supporting plate 49 (shown in detail in Fig. 5) has upwardlyprojecting ears 50 perforated at 51 to receive heade screws 52 by whichthe rear portion of the supporting plate is secured to the rear cross--bar of the carriage. Outwardly extending portions 53 on the sup ortinglate 49 rest upon inwardly extending brac et arms 54 which are formedintegral with the plates 37 and 38. Screws 55 are received inperforations in thebrackets 54 and take mtO threaded openings 56 in theprojections 53 to'secure the forward portion of the supporting plate tothe carriage. A trough or chute 57 has rearwardl extending ears 58 bywhich it is secured by screws 59 to the forward edge of the supportingplate 49. The forward portion of the chute is provided with an upwardlyextendin portion 57 formed with forwardl exten ing lugs 60 which projectover an are adapted to bear upon the front rail or crossbar 61 of thecarriage. The construction of the chute 57 is such that it extendslongitudinally of the platen and is adapted to receive the work sheetsor stencil plates as they are fed forward from the platen. Astencil-plate or worksheet holder or hopper 62 which is adaptedto'reccive and maintain the work sheets in a flat state is verticallydisposed in the rear of the platen and the rear wall of the hoppersecured to a depending flange 63 on the supporting plate by screws 64,whereas each side wall of the hopper is provided with a downwardly andoutwardly extending ear (3?; which is formedi tegral therewith andextends down throng a slit (35 in the supporting plate 49 and is securedto the bottom thereof by screws 66.

The upper edges of the hopper are bent outwardly, as indicated at 67 toprovide a flaring mouth for the hopper to readily reoeive and guide thestencil plates or work sheets into the hopper. ,The hopper is closed onthree sides and is open or cut away at just short'of the bottom thereof;terminat ing justabove the supporting plate 49 so as to provide ahorizontal slit or opening 7 (Fig. 3), through which the stencil platesmay be discharged one at a time. The

central portion of the supporting plate 49 is cut away to form anopening 71 Fig. 5) over which the hopper is mounted. Betfi een theopening 71 and the slits 65, there arefing'ers 73 (Figs. 3 and 5) formedfrom the". metal of the supporting plate 49. As

the sidewalls of the hopper rise perpenunder the right and leftdicularly from said slits, these fingers lie hand ends of the stencilplates or work sheets. The front of the hopper extends just forward ofthe free ends of-the fingers 73, whereas the rear wall of the hopper isadjacent to the flange 63.

Sprmgfingers' 74 are bent downwardly at the rear ends 75, thereof andare secured at their bent' ends to the depending flange column of 63 byscrews 76, the fingers extending forwardly above the fingers 73 and onpast the ends of said fingers, beneath the extreme platen roller,terminating near fingers thereof and constitute supports for the stencilplates 77 when said stencil plates are resting in the hopper and alsowhen th platen.

ey are being fed forward to the The stencil plates are each formed witha cardboard frame 78 having I a'reot'a'ngular central portion "79 whichis covered bythe sheeto r paper that is pasted stencil to the frame 7 8as indicated in Fig. 7. The

plates are arranged one on top of another, as shown in Fig. 3, anda'weight pressure toward the platen. the fingers 73 with a suitable toolthe width 80 which corresponds in shape to the inside opening of thehopper is arranged on top of the pile of stencil plates so as to forcethemdown as the stencil plates successively feed from the hopper, afinger piece 80 being provided on the weight to facilitate its removalwhendesired. Said weight is also shown-provided with corner posts 80 toprevent its being fed out through the slit when the pile of stencilplates is. exhausted. The forward ends of the fingers 74 are bifurcatedas indicated at 81, the slots in the bifurcated ends of the fingersextending beneath the serrated or toothed feeding wheels 48 -at-t-heends of the platen and the fingers exerting an upward spring By bendingof the slot 70 may be regulatedto permit 2) so as to 'prbpreferably halfrotation of the platen at a time. The tension 0 the spring fingers .74may be varied bybending them in the" p e same way inorder to regulatethe pressure. I

exerted by the fingers and cause them to properly cooperate, with thefeed wheels 48 to effect a forward feed of the stencil plates.

' It will thus be understood that the bottom of the hopper is entirelyopen except at each side thereof where the spring fingers 74'extendbeneath the hopper and constitute a support 'for the column of stencilplates and that said fingers actwith the side walls of the hopper as aguide to direct the stencil plates in their forward movements throughthe slot 70 at the bottom of Each side wall of the hopper has ahorizontal slot near the bottom thereof which receives-an inwardlyprojecting finger or follower 82 (Fig. 11) formedas a part of areciprocating slide 83'that moves fore and aft of the machine on thesupporting plate 49 and is guided in such movementby shouldered andheaded guide screws 84, the stems of said screws passing through slots85 in the slides and being received in openings 86 (Fig. 5) in andcooperating with nuts 87 (Fig. 3) beneath the supporting plate.

slides 83 is provided with an tending ear or lug 88, at the thereof (seeFig. 11). An outwardly extending pin 89projects from the ear 88 for theattachment of one end of a coiled conupwardly extractile spring 90,' theopposite end'ofs id spring being connected which projects outward thelower end thereof The tension of the springs 90 is thus exerted tonormally maintain the reciprocating discharging devices or slides 83 1ntheir rearmost positions, as shown in Figs. 2 and 11, where the inwardlyto a pin 91 (Fig. 2)

projecting fingers 82 thereof are just in the rear of the lowermoststencil plate and where they wiil engage the rear edge of said stencillate it forward movement of the slides 83 will, therefore, bring thefingers 82 into engagement'with the rear edge of stencil plate and willfo-rc'e this lowermost stencil plate forward in a flat state along'thefingers 74 and through the slit or opening 70, the side edges of thestencil plate being brought into cooperation with the serrated feedwheels 48. Each end of the platen carries two fixed actuating devices orpins 92 which are located diametrically opposite each other, as shown inFig. 2. tion of the parts is such that during each at each end thereofwiilfioe operation with the lug 88 Each of the forward end from thehopper at when the slides are moved forwardly;

A forward feed of a stencil plate 1n themanner just described forces it to a position where the forward portionof each side,

into engagement edge thereof is brought wheels 48 on the with theserrated feed platen as heretofore stated, and a further rotation of theplaten produces a forward feed of the stencil plate in a fiat statethrough the actuation of the serrated feed wheels and the cooperationtherewith of the spring fingers 74 which force the sides of the stencilplates into engagement with the serrated feed wheels. A continuedforward feed movement of the platen will eventually discharge theengaged stencil plate into the chute 57 and it will be directed in suchmovement under a guide finger 93 that projects at its free end towardthe platen and is secured at its forward end to the chute by a screw 94.7

As heretofore pointed out it requires but a half rotation of the platento effect a forward movement of the slides 83 to bring one of thestencil plates to position to cooperate with the platen. During theforward feed movements of a stencil plate with the platen the other setof oppositely disposed pins 92 are being rotated to a position wherethey will cooperate with the lugs 88 on the slides 83, when said slideshave effected a forward movement of the preceding stencil plate and 92which actuated them.

The platen shaft 36 has a line spacing wheel 95 secured thereto near theright-hand end of the shaft. This line spacin wheel, as shown in detailin Fig. 4, is provi ed with two series of ratchet teeth 96, 96 and'intervening plain or untoothed portions 97,

97 on which theline spacing pawl is adapt-- ed to ride freely withouttransmitting mo tion to the line spacing wheel as will hereinafter moreclearly appear. A detent roller 98 is carried by a spring 99 secured bya screw 1.00 to a downwardly and inwardly J projecting lug 101 formed onthe plate 38.

The detent roller bears against the periphery of the line spacing wheelin the usual manner. A line spacing lever 102 is pivoted at 103 to theand downwar ly extending arm or handle 104 by which. it maybe actuated.An upwardly extending arm- 105 on the line spacing lever projects aboveand to one side of the line spacing wheel 95 carries a line 'spacingpawl 106 of the lever at 10 The pawl has a leaf 65 spring 108 securedthereto at 108 and the:

ivoted on the inner side late 38 and has a forwardly free rearwardlyprojecting end of the leaf spring is received under a pin 109 whichprojects inwardly from the line spacing lever, the tension of the springbeing exerted to force the nose of the pawl toward the line spacinwheel. A stop pin 110 projects inwardly. rom the line-spacing lever andconstitutes a stop for the awl 106 to limit the upward movement of t eengaging nose thereof relatively to the lever. "An adjustable device orstop 11.1 coacts with the tail 112 of the pawl and determines the extentof line spacing movement that ma be given the platen at each actuation othe lever 104105. In the normal position of the parts the upwardpressure of the arm 104 brings the tail of t e pawl against the stop 111and forces the pawl against the tension of its spring 110 as shown inFig. 3. \Vhen the line spacing lever is actuated by turning it on itspivot 103 and against the tension of its spring 113, the tail of thepawl will be moved away from the stop 111 and the pressure of the spring108 will be effective to force the nose of the pawl into engagement withone of the teeth of the line spacin ratchet wheel and a further movement0 the line spacingrlever will effect a rotation of the platen. headjustable device for determimn the extent of line spacing movement is sown in detail in Fig. 6 and comprises the stop 111 .and a rotatingcarrier 114 therefor, the pin being off-set rom the center of thecarrier. This carrier is provided with a stem' or pivot 115 which is received in a bearing in the plate 38 and projects through the same to theouter side thereof where it is threaded at 116 for cooperation with afinger piece 117 by which the device may and rotated in its bearing toset the stop 111. in different positions. A coiled expan sion spring 118surrounds the pivot 115 and bears at one end against the finger piece117 and at its-other end against the plate 38 to exert an outwardpressure on the device.

The carrier or member 114 is provided with an outwardly projecting pinadapted to be seated in any one of several openings in the plate 38. Byan inward pressure on the piece 117 the member 114 may be moved to theleft in Fig. 6, thereby withdrawing the pin 119 from the opening 120 inwhich it is seated. The finger piece 117 may then be turned to bring thestop 111 in the desired position to determine the extent of line spacingmovement which is to be effected at each actua-' tion of a line spacingllever, and when pressure isreleased on t e finger piece the pin 119 willbe seated in an opening 120-to secure the device against rotation in itsadjusted position. i It will be understood that by adjusting the devicein the manner point 108 into contact with its stop be movedlongitudinally 119 which is exerting"- seas to force the sleeveand diskto the left. The pin 124 extends"through the disk so as to providealcckingpin 129 which into engagement with the ratchet wheel, de-

ending on-the adjustment of saiddevicei hile I have shown one means foraccomplishing this purpose it should be under stood that anysuitable'means for determining the extent of line spacing movement maybe employed.

The stencil plates have room for four or five lines of writing, andsaidplates are fed from-line to line by the line space mechanism justdescribed. When one stencil plate has been perforated, it is fed out ofthe machine and another is fed up to the first writing line by turningone of the finger wheels 39, 40. In order to arrest the platen when thefirst writing line is beneath the platen in position to be struck by theperforating types 13, I have provided a stop device which positivelyarrests the platen shaft'at this position and prevents further turningof said shaft by the finger wheel until after the linespace lever isoperated. This stop device'is adjustable to vary the position on thestencil plate of the first writing line.

Projecting rearwardly and downwardly from the line spacing lever is astop or arm 121 secured to the line spacing lever at 122. In'the normalposition of the line spacing lever this stop or locking arm or abutment1.21 is so positioned that it will extend into the path of stop orlooking pins or abutments 123, 124 which are carried by a disk 125 whichis locked to rotate with the platen. It will be understood,'- therefore,that a forward rotation of the platen by the finger wheel will bring oneof the stop pins into contact with the rear end of the stop arm 121 anda further movement of the platen in this direction by this meansis'prevented by such contact; the line spacing lever normally bearingagainst the member 114, as shown in Fig. 3, to prevent further upwardmovement of 'the rear arm of said lever. The disk 125 is rigidlyconnected to a sleeve 126 which surrounds the platen shaft and extendsthrough a bearing opening in the plate 38, the outer end of the sleevebeing provided with a finger piece 127 by which .the sleeve and the disk125 connected there- 'to may be moved longitudinally along the shaft.

A coiled spring 128 surrounds the platen shaft and bears at one endagainst the hub of the finger wheel 40 and at its opposite end againstthe finger piece 127 is'adapted to be received in any one of a number ofopenings 130 in the line spacing wheel so as to rigidly connect the diskand pins'l23 and 124 carried thereby, with the line spacing wheel. Sightapertures or openings 131 are provided on diametrically opposite sidesof-the disk 125 in the periphery thereof'j-and these sight openings areadapted to register with the indices or index numerals a on the outerface of the line" spacing wheel. The means just described affords anadjustment of the looking pins 123 and 124 relatively to the linespacing wheel and determines at what period in the rotation of theplaten the pins 123 and 124 will be brought'into contact with the stoparm 121- and determines at what period in the forward rotation of theplaten it will be arrested.

It will be seen that the indeii numerals a are arranged as follows O, 1,2, 3. An adjustment of the disk 125 so that a sight aperture l3l willregister with one of these index numerals positions the stops 123 and124 and indicates at how many line space distances from the top of eachstencil plate the first line of writing will appear, and, indirectly,how many line spaces may be written on each stencil plate before theline spacing mechanism will be rendered inoperative to turn the platenfarther, as will hereinafter more clearly appear.

When the line spacing lever is in the normal position the stop arm 121is in the path I of the stops 123 and 124 and will arrest the platen inits forward rotation when such forward rotation is efi'ected-by eitherof the finger wheels 39 or 40. Although the platen can no longer begiven a forward rotation by the finger wheels when one of the stop pins123 ,or 124 contacts with the end stoparm 121, the line spacing lever isnevertheless free to be actuated at this time. Thus an actuation of theline spacing lever at this time lowers the stop arm 121 away from theengaged stop 123 or 124 before motion is communicated to the platen andthe further movement of said line spacing lever effects a line spacingmovement or forward feed of the platen.

A rotation of the platen for a single toothed A ace distance moves thestop 123 or 124, which was engaged by the stop arm, forwardlyacorresponding distance and when the line spacing lever is released itwill be restored to the normal position; a cut-out portion or recess 132in the stop arm registering with the formerly. engaged pin 123 or 124,so that the pin and stop arm will not interfere with the line spacinglever being restored to normal position. The line spacing lever' may beemployed to effect a forward feed of the platen until one of the blankportions97, 97. isbrought into the path of the line spacing pawl whenthe line spacing mechanism is rendered inoperative and a further forwardfeed ofthe platen operates with the cams 14'2 cannot be effected by thismeans. The operator will therefore understand that further writing onthe stencil-plate cannot be effect ed, or that the last line on thestencil plate 5 has been reached. While the line s acing mechanism isino erative to effect a urther forward'feed of tile platen the fingerwheels 39 and 40 may at this time be employed to turn the platenforwardly in order to discharge the last written stencil plate to thechute and to automatically feed the next stencil plate forward intocooperation with the platen and into position to receive the first lineof writing. In other words, the operator may rotate either of the fingerwheels 39.01 40 to produce a forward movement of the platen until thenext succeeding stop pin 123 or 124 is brought into engage-- ment withthe end of the stop arm 121 to arrest further forward movement of theplaten through the finger wheels. This 'movement is sufiicient todischarge the stencil'plate which has been written and to antomaticallyfeed the next succeeding plate forward to proper position to receive thefirst line of writing.

It will be observed thatone stencil plate is fed out of the machine ateach half rotation of the platen, and that only a few lines are writtenon each stencil plate, so that the types 13 never strike the platenexcept along a few lines on each half thereof. The slot 41 is situatedbetween these two areas in a part of the platen that is never struck bythe ty es.

Vhen a stencil plate has been fed free of the platemit falls into thechute 57, and I have provided means for disehargingit from the left handend of said chute. The discharging device comprises a Vibratory oroscillating arm 133 pivoted at 134 and ressed in the direction of thearrow in ig. 2 by a spring 135, one endof which is secured at 136 in anopening in the supporting plate 49, the other end of the spring beingsecured at 137 to the vibratory arm The forward free end of thevibratory arm has an upturned portion 138 to assure. contact with thestencilplate. From an examination of Fig. 3 it will be seen that the arm133 is bent at 139 so that the free end of the arm may extend down inand adjacent to the bottom of the chute 57. A hub 140 is secured. by ascrew 141 to the platen shaft 36 and this hubv carries two oppositelydisposed cams 142, 143. The cam 142 is formed as an extension of aplate-like portion 142 (Fi 9) that is located in a plane at rightang esto the shaft'36 and in a like manner the cam 143 is provided with aplate-like member 143 which is likewise in a plane at right angles tothe shaft 36. An upwardly projecting half cylindrical pin 144 is carriedby the discharging device 133 and coand 1.43 as tin-.5;

striking against are rotated witlrthe shaft 36 to more the vibratorydischarging device against the tension of the spring The parts are sotimed that while the stencil plate is being fed forward by the serratedfeed wheels 43 one of the cams 142 or 143 will engage the pin 144 andwill positively more the vibratory arm 133 against the tension of thespring 135. After the stencil plate engaged by-the feed wheels 48 hasbeen discharged into the chute and under the guide finger 93, the camwhich engages the pin 144 will be moved to a position where the abruptdrop or straight edge thereof will. clear the pin, thus relmsing it. Thearm will be forced by its spring in the direction of the arrow in Fig.2, thus bring the upturned end 138 into engagement with the right-handedge of the stencil plate and the force of the arm 133 the stencil platewill force it along the chute 57 and discharge it from the machine atthe left-hand end of said chute. The movement of the arm 133 justdescribed is arrested by the pin 144 engag ing the plate-like portion142- or 143 of the next succeeding cam so that it is in a position tocooperate with the next succeeding cam during a further rotation of theplaten in order to place the spring 135 under tension and thenautomatically release the arm to discharge the nextstencil plate thathas been fed fdrward into the chute by the serrated feed wheels 48.

Having described'the construction I Wlll now proceed to describe indetail the operation of the machine.

The operator first determines how many line spaces are to be written oneach stencil plate or work sheet 77 and where the first line of writingis to appear by adjusting the disk, carrying the stops 123 and 124, onthe line spacing wheel T ins if the operator desires to produce thefirst line of writing at, say, two line space distances or the distanceof two teeth of the line space wheel from the top writing edge of thestencil plate, the disk'125 will be set so that the index numeral 2 willbe exposed at the si ht openings131 in the disk and when the filaucn hasbeen rotated forwardly until it is arrested by one of the stop pins 123,124 coming into contact with the stop arm -1J1 the stencil plate will beproperly positioned to receive the impact of the puncturing points Itthe line indicated. After this line has been completed the operator mayactuate the line spacing mechanism to feed the stencil plate to writeor. perforate other lines. After three line space distances or thedistance of three teeth of the line spacing ratchet whcr-L one of theblank portions 97 or 97 of the ratchet wheel will be brought into coti'icration with the line spacing pawl and a further movement of theplaten cannot be effected by the line spacing mechanism. The forwardsEsT AVAILABLE cos feed of the platen thus roduced by the line spacingmechanism wil bring the stencil plate to a position where the last lineof writing may be produced near the lowermost portion thereof or thatportion of the stencil plate which is near the lower edge of the frame78. No matter what adjustment is given to the stops 123, 124 the linefeed mechanism will always be rendered inoperative before the lower edgeof a stencil plate. is brought to the printing line by one of the blankor untoothed portions 97 or 97 being brought into cooperation with theline spacing pawl. The operator may effect a further forward feed of theplaten by the finger wheels 31) or 40 after the last line of writing hasbeen produced on the stencil plate in order to discharge the completedstencil plate into the chute and to automatically effect a forward feedof the next succeeding stencil plate. After the mechanism has been set.in the manner described the operator may fill the hopper with stencilplates or work sheets and lace the weight in position thereon. The rststencil plate is fed to operative position to receive the first line ofwriting by the combined operation of the line spacing mechanism and thefinger wheels 89 or 40; the line spacing mechanism being actuated firstand the final movement of the stencil plate being effected by either ofthe finger wheels. \Vhen a further rotation of the fin er wheels isprevented by one of the loc ing members or stop pins 123, 124 coininginto contact with the stop arm 121 the stencil plate will be in positionto receive the first line of Writing and the slides 83 which moved saidstencil plate forward will have been released from the pins 92 whichactuated them and will be restored by their springs to the normalposition shown in Fig. 2 where they are ready to effect a forward feedof the next stencil plate which is the lowermost stencil plate supportedon the spring guide fingers 74. The operator may now proceed with thewriting and as the successive lines are written and the line spacingproduced by the line spacing mechanism, one of the blank portions 97 orf)? on the line spacing ratchetwheel will be brought to a position Wherethe. line spacing pawl will cooperate therewith before the bottom of thestencil plate has been reached. This will render the line spacingmechanism inoperative to produce a further forward feed movement of theplaten, thus notifying the operator that the last'line on the stencilplate has been reached. After this line has been completed the operatorwill turn the platen forwardly through the finger wheels 39 or 40 untilfurther movement. is arrested by one of the stop pins 123, 124 cominginto contact with the stop arm 121. This last mentioned movement of theplaten through the finger wheels 39 or 40 is effective to bring theother set of pins 92 into contact with the upwardly pro ccting lugs orcars 88 on the slides to si1nultaneously move them forward in order toautomatically effect a forward feed of the next stencil plate as thecompleted plate is being fed forward into the chute by the rotation ofthe platen. The same movement is also effective to move the dischargingdevice 123 against the tension of its spring and the parts are so timedthat when the completed stencil plate is discharged into the chute andthe next succeeding stencil plate is in operative position to receivethe first line of writing the discharging device 183 will beautomatically released and will strike the stencil plate in the chuteand drive it along the chute and out of the machine. After thisoperation has been completed further forward rotation of the platen bythe actuation of the finger wheels is prevented through the engagementof one of the stop pins 123 and 12 i engaging the stop arm 121. It isnecessary, therefore, to proceed with the writing and to effect afurther forward movement. of the platen through the line spacingmechanism. These operations are continued until the stencil plates areexhausted and the front. of the hopper being open enables the operatorto observe when it is necessary to refill the hopper.

It. will be observed from the foregoing description that the fingerwheels 39 and 40 and the line spacing mechanism are alternately operatedto effect. a forward feed movement of the platen; that after apredetermined extent of movement. by either of the devices in questionsaid device is rendered inoperative to effect a further forward movementof the platen until the other device is actuated; that in this mannerthe stencil plates are successively brought to proper position toreceive the first line of writing and as the writing proceeds thestencil plate in operative position is arrested from further movementbefore the bottom thereof is presented to the print.- ing line: thatafter the stencil plate is completed the other device, or either of thefinger Wheels 39 and 40 may be employed to effect a further forward feedof,tbe completed stencil plate to discharge it from the platen into thechute; that the plate in the chute will be automatically discharged fromthe machine and the next succeeding stencil plate will heautoi'natically brought into operative position: that the predeterminedextent of forward movement of tilt platen effected by said finger wheelsis determined by the cooperation of the locking devices 121, 123 and 12fand positiveli regulates the positioning of the stenci plates in themachine. to receive. the first aiu ast lines of writing and that theadjust ment of the disk 125 is effective to vary th positioning of thestencil plate corresponding to the character of the work to be produced.

It will also be seen that the'feed of the work sheets or cards from thehopper to the platen is positively effected by the positive engagementof the positively actuated fingers 82 with the cards and that the cardsor stencil plates are maintained in a fiatstate from the time they arereceived in the hopper until they are discharged from the machine ascompleted stencil plates.

Various changes may be made without departing from my invention.
